Bug: Hitting <C-l> does not immediately clear results from searchcount component

[camoz]

Self Checks

• [x] I'm using the latest lualine.
• [x] I didn't find the issue in existing issues or PRs.

How to reproduce the problem

1. have lualine configured to use searchcount component
2. search something in the buffer, e.g. input /a<CR>
3. observe how searchcount component becomes visible
4. press <C-l> to clear highlighting of current search results

Expected behaviour

searchcount component becomes instantly invisible.

Actual behaviour

searchcount component does not become instantly invisible. It becomes invisible after the remaining time until lualine refreshes.

Minimal config to reproduce the issue

Lualine default config with following changes:

• searchcount component added to section lualine_x
• increase statusline refresh to 3000 ms, to make issue more visible

require('lualine').setup {
  options = {
    icons_enabled = true,
    theme = 'auto',
    component_separators = { left = '', right = ''},
    section_separators = { left = '', right = ''},
    disabled_filetypes = {
      statusline = {},
      winbar = {},
    },
    ignore_focus = {},
    always_divide_middle = true,
    globalstatus = false,
    refresh = {
      statusline = 3000,
      tabline = 1000,
      winbar = 1000,
    }
  },
  sections = {
    lualine_a = {'mode'},
    lualine_b = {'branch', 'diff', 'diagnostics'},
    lualine_c = {'filename'},
    lualine_x = {'searchcount', 'encoding', 'fileformat', 'filetype'},
    lualine_y = {'progress'},
    lualine_z = {'location'}
  },
  inactive_sections = {
    lualine_a = {},
    lualine_b = {},
    lualine_c = {'filename'},
    lualine_x = {'location'},
    lualine_y = {},
    lualine_z = {}
  },
  tabline = {},
  winbar = {},
  inactive_winbar = {},
  extensions = {}
}

Additional information

Neovim 0.10 by default maps <C-l> to <Cmd>nohlsearch|diffupdate|normal! <C-L><CR>, see :nmap <C-l> and :help default-mappings.

Workaround:

-- Overwrite neovim's <C-l> mapping using : instead of <Cmd>
vim.keymap.set('n', '<C-l>', ':nohlsearch|diffupdate|normal! <C-L><CR>')

I think this works because :, unlike <Cmd>, triggers a mode change, and lualine refreshes on ModeChanged.
